Product Details
These tubes and caps have been designed for the storage and transportation of biological material. They are manufactured from non-toxic polypropylene, offering strength and clarity. The vial features external threads, providing a smooth and uniform inner surface that reduces the risk of contamination. The screw caps, also made of polypropylene, maintain the same coefficient of expansion as the tubes, ensuring a leakproof seal even at changing temperatures. The caps come with a long skirt and a super-fast thread design, allowing for easy removal or sealing with a single turn. Additionally, they are available with or without a silicone O-ring and in a variety of colors. Screw caps are sold separately, ensuring compatibility with the tubes for effective storage solutions.
